Results showed that the PMC meiosis of autotetraploid was similar to the diploid except some particularities. In metaphase Ⅰ, multivalent, quadrivalent, trivalent, bivalent and univalent were observed and some of the chromosomes were found not to rank on the metaphase plate and so did in metaphase Ⅱ cells. In anaphase Ⅰ and anaphase Ⅱ cells, there were lagging chromosomes, chromosome bridge and fragment. During anaphase Ⅱ and telophase Ⅱ, chromosome segregation was not synchronous or equal. At tetrad stage, dyad, triad, tetrad with micronucleus and polyad appeared.

结果表明，同源四倍体花粉母细胞减数分裂过程与二倍体相比，中期Ⅰ染色体构型复杂，有多价体、四价体、三价体、二价体和单价体；中期Ⅰ及中期Ⅱ有部分染色体没有排列在赤道板上；后期Ⅰ及后期Ⅱ出现落后染色体、染色体桥及断片；后期Ⅱ和末期Ⅱ有染色体不同步分离及不等分裂的现象；四分体时期还出现二分体、三分体、含微核的异常四分体及多分体。

Three different populations of diploid potato were employed to study chip color in this experiment. Seven different processing traits among the three populations were analyzed. According to a certain program of chip processing, all genotypes in three populations were evaluated strictly on their chip colors. The molecular markers of chip color genes were studied with the method of Bulked Segregant Analysis.

本研究选用了3个不同组合的二倍体马铃薯炸片群体材料，在群体间对7个不同的加工性状进行了比较分析，按照一定的炸片加工程序对3个群体所有单株进行了炸片颜色鉴定，并采用混合分组分析方法进行了马铃薯炸片颜色基因的RAPD标记。

To induce diploid gynogenesis in summer flounder, eggs were fertilized with heterogenous cryopreservative sperm of Lateolabrax japonicas , which was irradiated with UV ray to be genetically inactivated, and cold shock was used to prevent extrusion of the second polar body.

中文摘要：用冷冻保存的花鲈精子作为异源精子，采用紫外线对精子进行照射使其遗传物质失活，然后与卵子进行"授精"，可以刺激犬齿牙鲆鱼卵进行雌核发育，在受精后一定时间采用冷休克处理"授精"卵，抑制第二极体排出成功获得了犬齿牙鲆雌核发育二倍体鱼苗。

The ovary of Phyllostachys praecox had one anatropous ovule. The crassinucellate ovule had diploid integuments. The monosporic embryo sac had one tetrad which turned on line and many antipodal cells. The synergid had the obvious filiform appratus.

The results showed as follows: The diploid chromosome number of Yanbian yellow cattle and Liyan hybrid cattle were 2n=60,the karyotype of bulls was 2n=60,XY,while cows were 2n=60,XX. 29 pairs of autosomes were telocentric.

采用外周血淋巴细胞培养技术、常规染色体制片技术和染色体C-分带技术，对延边黄牛(10♀，10♂)和利延杂交牛(14♀，15♂)两品种的染色体核型和C-带进行了研究。

Primary culture and subculture were adopted using lung cells of a female Elaphodus cephalophus' embryo. A new karyotype and a pair of big telocentric chromosomes were found. The diploid has 48 chromosomes, and the karyotype formula is 2M+2ST+42T+XX. C-banding analysis shows that these chromosomes are homologous with those reported relevant chromosomes. This article is the first to report the polymorphism of Elophodus cephalophus B-chromosomes and studies it's transmitted mechanism.

采用原代培养和传代培养法，对1头毛冠鹿的胚肺组织细胞进行观察，发现一种新的核型，其二倍体染色体数目为2n=48，核型公式为2M+2ST+42T+XX，出现1对大的末端着丝粒染色体，C-带显示该染色体与已报道的相关染色体同源，首次提出毛冠鹿B染色体多态，对其传递机制进行了探讨。
